This is the second installment of Jim's and Sarah's adventures. This one has more sex and probably less of a build-up before sex. I'll continue this story as time lets me. I hope you enjoy it. I appreciate any and all comments.nnChapter 2. nnA few hours after cumming all over my sexy sister (and becoming her sex slave) I had downloaded all the pictures to my computer and sat reviewing them when Sarah came in to my room. The pictures were extremely sexy and I had another hard-on from looking at several hundred pictures of an extremely sexy woman posing. The fact that the woman on the pictures was my sister and the cock the spewed cum all over her was mine didn't exactly lessen my arousal. Not at all. Seeing the images and thinking of that session was enough to almost make me cum again, without even touching myself.nn"What, are you not dressed yet? You really need to get ready quickly since you're taking me to dinner tonight!" Sarah looked awesome in a flower print summer dress and sandals. But she looked mad too.nn"I didn't know, Sarah! You never told me, did you?" I was annoyed as I turned around to look at her. I only wore a pair of sweatpants and my hard cock tented the trousers very visibly. Sarah's eyes focussed on my groin and a strange look came to her eyes.
